a$.$ Prepare a Planning Chart for the application.

b$.$ Draw a sketch of an appropriate interface. If you want to include an image in the interface, you can either use your own image file or download an image file from the internet.

c$.$ Create a Windows Forms application. Use the following names for the project and solution, respectively: Area Project and Area Solution. Save the application in the VB$9$e $\frac{\frac{?}{?}}{?}$ Chap $02$ folder. Change the appropriate properties of the form. Also, be sure to verify the name of the startup form.
